Method and system for hydrating and calibrating an electrochemical sensor

Methods and systems for hydrating and calibrating an electrochemical sensor are disclosed. The method comprises providing an electrochemical sensor, providing a calibration solution to a measuring chamber of the electrochemical sensor, contacting the sensor with the calibration solution within the measuring chamber, exposing the sensor and the calibration solution to an elevated temperature, and over a cooling period, cooling the sensor and the calibration solution with a tempering device, wherein the temperature is controllable within a device error range of temperature, performing a plurality of calibrations of the sensor, wherein a calibration of the plurality of calibrations is valid for a calibration margin of temperature error, the calibration margin of temperature error exceeds the device error range of temperature, and controlling a decrease of the temperature of the sensor and the calibration solution not to exceed the calibration margin of temperature error between consecutive calibrations of the sensor.
